London, England (CNN) -- Film-maker Joss Whedon says he wants to buy the rights to the multi-million dollar "Terminator" franchise -- not for millions, or hundreds of thousands of dollars, but for ten grand.

After four movies and a TV series, the franchise does not seem to pack the same punch as it once did at the box office.

This year's "Terminator: Salvation" starring Christian Bale took in $371 million worldwide, according to boxofficemojo.com.

By comparison, 2003's "Terminator 3: Rise of the Machines," which, unlike its sequel, did at least feature Arnold Schwarzenegger, took in $433 million.

Nevertheless, rights to make new Terminator films are expected to garner more than $60 million at auction, as first reported by the Financial Times.

The rights to make future "Terminator" movies, TV shows, games and DVDs are being auctioned after current owner Halcyon sought bankruptcy protection. Halcyon paid $25 million for the rights two years ago.

FTI Consulting, which is managing the auction, told CNN that major film studios, independent producers and investment funds are all following the sale.

Whedon's bid may be far fetched, but the letter -- written in characteristically irreverent style -- has bloggers and fans wondering just how serious he is about reworking the franchise.

New York Magazine's Vulture blog referred to Whedon as being a "facetiously interested" bidder while fans on Whedonesque offered to pitch in for the cause.

One fan commented: "Hey, I've got... let's see... $14.85 right here. I'll gladly add it to the pile of anyone who'll bring us some more proper Terminator."

In his letter, posted on Monday, Whedon writes: "The 'Terminator' story is as formative and important in our culture -- and my pretend play -- as any I can think of. It's far from over."

Whedon, the force behind the "Buffy" and "Angel" TV series, as well as the short-lived "Firefly" and new show "Dollhouse," outlines six apparently jokey ideas for the franchise in the letter.

He writes: "Christian Bale's John Connor will get a throat lozenge. This will also help his Batwork (ten grand for that franchise too, btw.)"

Whedon also suggests sending a Terminator to Middle Earth, who helps because "he's a cyborg and he doesn't give a s#&% about the ring -- it has no power over him!"

But Whedon, who wrote the memorable "Once More, With Feeling" musical episode of "Buffy," draws the line at incorporating song into the "Terminator" concept.

"Can you say ... musical? Well don't. Even I know that's an awful idea," he says.

But under his direction, "the movies will stop getting less cool," Whedon writes.

Kevin Shultz, senior managing director at FTI Consulting who is leading the deal, told CNN that he was not aware of any serious proposal made by Whedon.

Whether a $10,000 bid would be even considered in an auction expected to fetch tens of millions, Shultz said: "The numbers speak for themselves."

And Whedon, who ranks high in geekdom, admits he may not be a serious contender.

"... Mostly, it's just me being a dumb-ass, because that seems to be what I do best -- I'm not even very good at that. So, no, I do not think they're going to call me and say 'Congratulations! We'll have that $10,000 now,'" he told EW.com.

But there is a sincerity of sorts behind his far-fetched bid.

"I adore the franchise. I literally did learn a huge amount from that [franchise]. ["The Terminator"] came out when I was in college, and I was like, This is how you construct a story. It's very important to me. That part was true. The part where I think I'm going to get it, not so true," he was quoted as saying.
